Patent number: 8729289Abstract: A method for performing a flying grade switch in an ester production process, which preferably is operated in semi-continuous mode, maximizes plant equipment productivity while minimizing product cross-contamination. Mixed ester products of the process containing a C9-C11 alkyl or isodecyl benzoate together with a higher molecular weight di-alkyl phthalate or cyclohexanoate, bring performance advantages such as improved permanence in plasticized PVC articles or improved processability in manufacturing these articles.Type: GrantFiled: March 7, 2008Date of Patent: May 20, 2014Assignee: ExxonMobil Chemical Patents Inc.Inventors: Nicolaas Anthony De Munck, Allen David Godwin, Thomas Marshall Larson, Paul H. Daniels, Didier Naert

Patent number: 8283411Abstract: Esters of cyclohexane polycarboxylic acids are used as plasticizers for polyvinyl chloride to enable products with comparable mechanical properties to be obtained using less polyvinyl chloride. Use of these esters also produces formulations with increased stability to ultra-violet light, improved low temperature properties, lower viscosity and improved processability as well as reduced smoke on burning. The esters of cyclohexane polycarboxylic acids may be used alone or in admixture with other plasticizers when the esters of cyclohexane polycarboxylic acids may act as viscosity depressants. Fast fusing plasticizers may also be included. The formulations are particularly useful in the production of a range of goods from semi-rigid to highly flexible materials and are particularly useful in the production of medical materials such as blood bags and tubing.Type: GrantFiled: November 21, 2011Date of Patent: October 9, 2012Assignee: ExxonMobil Chemical Patents Inc.Inventors: Claudius Gosse, Thomas Marshall Larson, Pierre Jean Paul Legrand, Raphael Frans Caers, Paul H Daniels, Allen D.
